The Pro-B4 is the state-of-the-art battery generator. In some regards it even outperforms the best studio generators out there. Just try finding another generator that can freeze motion at 1/25,000 second or fire up to 30 flashes per second! That is why we are not afraid to label it a revolution on location.

Unrivaled flash durations on all power settings.

Selectable FREEZE mode available for extreme splash shots.

The world’s fastest recycling battery generator, allowing you to create never before seen sequence shots on location.

Next generation Li-Ion (LiFe) battery recharges to full power in only 45 minutes.

Battery can be charged while in use, which makes the generator equally useful in the studio!

Two individual outputs and 11 f-stop power range with control in 0.1 f-stop steps provides unbeaten precision and versatility on location.
